Bug: HeadPose.Equals throws NullReferenceException

[HEGIT-TBL]

Installed product versions

Product Type	Name	Version
Visual Studio	VS 2022 community	v17.7.4
NuGet Package	FaceRecognitionDotNet.CUDA112	v1.3.0.7

Description

HeadPose's equality method/methods do not take null into consideration and throw System.NullReferenceException.

Steps to recreate

Run the following code with NuGet package installed

using FaceRecognitionDotNet;

HeadPose hp = null;
var isNull = hp == null;

Expected behavior

As per MSDN:

Implementations of Equals must not throw exceptions; they should always return a value.

So in this case hp == null should return true

Current behavior

hp == null throws System.NullReferenceException at FaceRecognitionDotNet.HeadPose.op_Equality(HeadPose pose1, HeadPose pose2)
